Scale bars
Scale bars provide a visual indication of the size of features and distance between features on the map.


Scale bar elements
When the scale of the data frame changes, the scale bar will automatically be updated to reflect the new scale. For scale bars to be displayed correctly, it is important that the map units property for the data frame is set.

Scale Bar - A map element which shows the scale of a map graphically.
Set - A group of features and their data.
Spatial - (pro. Spay-shawl) An adjective. Of, relating to, or occurring in space.

Scale Bar - A map element used to graphically represent the scale of a map. A scale bar is typically a line marked like a ruler in units proportional to the map's scale.

scale barA map element that shows the map scale graphically.
scanningThe process of capturing data in rasterformat with a device called a scanner. Some scanners also use software to convert raster data to vector data.

Use the Scale Bar found at the bottom of every National Topographic Systen (NTS) map to determine distances between points or along lines on the map sheet. (Note, the example below is not to scale.) ...

the Scale Bar will remain correct
the written Statement of Scale will not be correct ...

Creates a scale bar frame - inserts a scale bar that corresponds to the view, scale is in the map units specified in the view
Creates a north arrow frame - inserts a correctly located north arrow ...

To change the scale bar units to "meters," click on the pointer button , which is the first button on the left in the second row of buttons at the top of the screen.

Select Object->Scale Bar in the Annotation dialog.
Enter the desired parameters, then place the scale bar using the left mouse button.
Lock in the annotation using the right mouse button.
Declination ...

Scale Bar - Is a visual expression of the relationship between ground coordinate space and that if the map page space. (Clarke, 2001) ...

[map design] The arrangement of elements on a map, possibly including a title, legend, north arrow, scale bar, and geographic data.
[ESRI software] In ArcGIS, a presentation document incorporating maps, charts, tables, text, and images.

Titles, Legends, Scale Bars, and North Arrows are all forms of Map Annotation. Functionally they are used to depict information concerning the map.

-m Use mouse to interactively place scale -f Use feet/miles instead of meters -l Draw a line scale instead of a bar scale -t Write text on top of the scale, not to the right -n Draw a north arrow only -s Draw a scale bar only ...

It is usually printed on the map to the left of the scale bar at the bottom of a USGS 7.5' quadrangle. After finding the declination on the map, you need to transfer the information to your compass before you ever take it into the field.

Templates can contain data, a custom interface, and a predefined layout that arranges map elements, such as north arrows, scale bars, and logos, on the virtual page. Map templates have a .mxt file extension.

It may also contain additional graphical elements such as scale bars, north arrows, text, images, and geometric shapes (drawing objects).

For example, a map element can be a title, scale bar, legend, or other map-surround element.

Caption options enable users to create highly-customizable scale bars that contain extra information - 11 different North Arrow styles are provided ...

Step 3 From the View menu, select Scale Bar Properties, Map Units, Meters as shown below.

In ArcGIS, set up your map symbology, add a legend, scale bar, and any other map elements that are necessary.

Next we will create a map layout for our greater context map. We will add a title and a scale bar some text that labels our are of interest. We will take a look at legends.

An important property of a map is the scale. It can be indicated by a scale bar and/or a ratio 1:n. This enables the map user to measure a distance on the map and determine the distance on the ground.

An alternative method of indicating the scale is by a scale bar. This can also be applied on a computer screen etc., where the ratio may vary, and also remains valid when enlarging or reducing a paper map.
